“…reactor similar to that used in the previous bench-scale work but located in a shielded cave to permit a study using irradiated fuels. The objectives of this study were (1) to establish if fission products or the presence of a radiation field has a significant effect upon uranium recovery from uraniumalloy fuels, (2) to determine what uranium decontamination factors were possible, and (3) to determine the uranium and fission-product distribution following each process step.…”
